CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 231,127, dated August 10, 1880,

Application filed March ,2, 1880.

To all whom it may concern Be it known that I, LoUIsB. WEIsENBURGH, of Frankfort, State of Kentucky, have invented certain new and useful Improvements in Car- Oouplings; and I hereby declare the following to be a full, clear, and exact description thereof, reference being bad to the accompanyin g drawings, making part of this specification, and in which- Figure 1 is a plan view of the coupling as it appears with the cars coupled. Fig. 2 is a horizontal longitudinal section, showing the operative parts in the draw-head.

The object of my invention is to provide an automatic car-coupler wherein the couplinglink will be seized when the cars come together, and wherein the cars may be uncoupled without the brakeman passing between them; and my invention consists of draw-heads containing two spring clamping-jaws to seize a coupling bar or link provided with barbed ends, said springjaws being provided with lugs which project through the draw-head and come in contact with a cam, which is operated by a lever or other suitable means, in order to retract or release the spring-jaws.

In order that those skilled in the art may make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

In the said drawings, Arepresents the drawhead, being enlarged at a a to receive within it two pivoted jaws, B B, behind each one of which lies a spring, I) I), keeping the jaws normally closed. The jaws come together at a point immediately in front of the opening 0 for the reception of the coupling-link K.

Each springjaw is provided with an upwardly-projecting lug, Z Z, passing through slots 8 s in the upper side of the draw-head, where they rest against the edge of a double cam, E, which turns-on a pivot, e.

The eccentric cam is operated by a lever, L,

(ModeL) pivoted at right angles to the draw-head, and connected to the cam by the link H and pin h. It will be seen that as the cam is turned the spring-jaws are retracted and their hold on the barbed couyfling-link K released. The cam being operated through lever L, the brakem an has no need to pass between the cars.

It might happen that the spring-jaws would be retracted when two cars come together and there would be no provision for seizing the link. To avoid this I insert through the face of the draw-head a spring-pin, P, which has an upwardly-projecting lug, t, on its rear end, fitting into a recess, 2', on the lower face of the cam on one side of its pivot, so that when the cam is turned to retract the spring-jaws the pin P is forced forward and the lug t lies against the edge of recess t". The center of the coupling-link is provided with a disk, N, of such a circumference as to cover the face ofthe drawhead. When the cars come together and the barbed head of the coupling link or bar enters the draw-head, should the spring-jaws be retracted the pin I will be projecting, the disk N strikes pin 1?, which, by means of lug t and recess i, forces the cam around and releases the jaws, and allows them to spring together and seize the end of the coupling pin.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The draw-head A, provided with slots 8 s, and the barbed coupling-link K, in combination with the pivoted spring-jaws 13, provided with upwardly-projeeting lugs Z Z, the cam E, spring-pin P, provided with lugs i, lever L, and link H, all constructed, arranged, and operated substantially as and for the purpose set forth.
